The air return pipe 70 is arranged in the fourth avoiding groove 66, so that the air return pipe 70 is protected, and the volume of the refrigerating unit is not increased by the air return pipe 70.

Optionally, a fourth relief groove 66 extends through the sidewall 62 of the insulating member in an up-down direction.

Optionally, the top of the side wall 62 of the heat-insulating member is provided with a dodging port 68, and the air return pipe 70 passes through the dodging port 68 to be connected with the refrigerant outlet end of the evaporator 10, so that the air return pipe 70 does not protrude out of the top of the side wall 62 of the heat-insulating member, and on one hand, the air return pipe 70 is protected, and on the other hand, the volume of the refrigerating unit is reduced.

Optionally, the water pan 3 is located inside the installation space and is attached to the bottom wall 61 of the insulating member. The shape and the size of the water receiving disc 3 are respectively matched with those of the heat preservation piece 6.

The bottom wall 61 of the heat insulating member is provided with a communication hole 67 through which the drain pipe 36 passes so that the drain pipe 36 communicates with the outside.
